%0 Journal Article %T Light Interactions of Turkish Seas %A Fethi BENG£¿L %J - %D 2019 %X In this study, data sets obtained by satellite remote sensing were used to understand light characterization and sea waterlight interactions and evaluate inter-annual trends between September 1997 and March 2017. Photosynthetically active radiation (PAR) in terms of light intensity, and Euphotic depth (Zeu) and attenuation coefficient (KdPAR) in terms of lightseawater interaction were used for descriptive and time series analysis. As a result of this study, PAR showed no differences over the time period, while Zeu (mostly increasing) and KdPAR generally showed significant trends in the regions. It can be concluded that optically active constituents determine the interaction rather than light intensity in the regions. Additionally, it is expected that using these parameters in modelling studies will provide an advantage on reducing uncertainties that come from globally used bio-optical empirical relationships %K T¨¹rkiye denizleri %K £¿£¿£¿k %K fotosentetik olarak aktif £¿£¿£¿ma %K £¿fotik derinlik %K s£¿n¨¹mlenme katsay£¿s£¿ %U http://dergipark.org.tr/actaquatr/issue/43483/478155
